Typical post about weight gain :p

Shiara • Im an 18 year old FTM, engaged to the love of my life, the beautiful man who gave me my perfect little son 😍 15/18/16💙
Im 28w with my first and ive already gained more than im supposed to during this whole pregnancy.. I started off at 110, and am now at 140... Can this hurt the baby? Im not worried about me being fat, just about him.. (Posted a before and now picture) lol
